Application filed May 23,

The object of this invention is to produce a tool in the nature of awrench for use by automobile mechanics which shall be of a constructionto permit of the device being operated to unscrew nuts from bolts inplaces where the same are not readily accessible to engagement by anordinary wrench.

'lo the attainment of the foregoing and other objects which will presentthemselves as the nature of the invention is better understood,reference is to be had to the drawing which accompanies and which formspart In the drawing Figure l is a view illustrating the arrangement ofthe tool for removing the nuts from bolts on the crank case of anautomobile.

q'irre 2 is an enlarged view of the tool.

in carrying out my invention, 1 provide a straight shank 1 with anoffset portionadjacent one of its ends providlng the shank vith arightangular handle 2/ The shank outward of the handle has swiveledthereon a head T he shank has its opposite end bent to provide aiE-shaped extension disposed in the direction of the handle 2 but of alength less than mat of the handle. The arm 4. of is disposed nearestthe handle 11 5 having its extremity enand bifurcated. and beingprovided *erse opening to receive there h the shank of a socket 6. Onthe n the portion thereof received in the cd end of the arm 5 there istoothed designed to have the teeth on either o'f laces engaged byoppositely arranged spring; influenced dogs 8, the said dogs having:their tail portions engageahle by cam surfa es on a niillet sleeve 9that surrounds the bifurcated end of the arm 5. The sleeve is limited inturning by the contacting engagement of a pin 10 with the opposed Walls1923. Serial No. 640,959.

or shoulders formedby notching the inner edge of the sleeve. When thesleeve is turned to one position, one of the dogs will engage the wheel7 to turn the socket 6 in one direction with the turning of the handle2, and when turned to an opposite direction the sec end dog will engagethe Wheel to turn the of th shank 1 will evade the edge of the enginecrank case during the tightening or loosening of the nuts thereon, whilethe space between the arm 4 and the handle 2 permits of the wrenchturning without contacting the radius bars of the machine. The wrenchis, of course, susceptible to other uses in connection with anautomobile and like mechanisms, but it is thought that the foregoingdescription when taken in connection wi h the. drawing will amply setforth the construction and advantages of the improvement.

Having described the invention, I claim In tool for the purpose setforth, a straight shank having a head swiveled to one end thereof, arightangular handle formed therewith inward of the head and its secondend formed with a U-bend extended in the same direction and arranged inthe same plane as the handle, the outer arm of the U-hend being enlargedand bifurcated, a socket member in said bifurcated end and a ratchetmechanism associated with said socket member and the axial plane of thesocket being in a line with that of the shank.

In testimony whereof I afiiX my signature.
